	Beta
(Constant)		2.238	0.03	1.170 ~ 18.200	12.228	< 0.01
Purpose-designed item 6	0.127	2.298	0.02	0.221 ~ 2.862
Occupational stress	0.220	4.155	< 0.01	1.518 ~ 4.248

Maternal physical condition during pregnancy	0.167	3.085	< 0.01	1.050 ~ 4.750
Empathic concern	0.158	2.875	< 0.01	0.126 ~ 0.671
Planned pregnancy	0.105	2.061	0.04	0.106 ~ 4.591

R² = 0.220, Adj. R² = 0.202

Purpose-designed item 6 (1 = poor, 2 = ordinary, 3 = good and 4 = very good); occupational stress (1 = high, 2 = ordinary, 3 = low or none); adherence to scientific dietary recommendations (1 = no, 2 = yes); educational level (1 = junior high school or below, 2 = senior high school, 3 = college, 4 = undergraduate or above); maternal physical condition during pregnancy (1 = poor, 2 = ordinary, 3 = good); and planned pregnancy (1 = no, 2 = yes)

The direction is indicated by the sign of the standardized coefficient: positive coefficients ( +) indicate a positive relationship (better outcomes with higher scores)
